openSTARS: An Open Source Implementation of the 'ArcGIS' Toolbox 'STARS'

An open source implementation of the 'STARS' toolbox
(Peterson & Ver Hoef, 2014, <doi:10.18637/jss.v056.i02>) using 'R' and 'GRASS GIS'.
It prepares the *.ssn object needed for the 'SSN' package.
A Digital Elevation Model (DEM) is used to derive stream networks
(in contrast to 'STARS' that can clean an existing stream network).
